+# Contributing Code
+
+PXT accepts bug fix pull requests. For a bug fix PR to be accepted, it must first have a tracking issue that has been marked approved. Your PR should link to the bug you are fixing. If you've submitted a PR for a bug, please post a comment in the bug to avoid duplication of effort.
+
+PXT also accepts new feature pull requests. For a feature-level PR to be accepted, it first needs to have design discussion. Design discussion can take one of two forms a) a feature request in the issue tracker that has been marked as approved or b) the PR must be accompanied by a full design spec and this spec is later approved in the open design discussion. Features are evaluated against their complexity, impact on other features, roadmap alignment, and maintainability.
+
+These two blogs posts on contributing code to open source projects are a good reference: [Open Source Contribution Etiquette](http://tirania.org/blog/archive/2010/Dec-31.html) by Miguel de Icaza and [Don't "Push" Your Pull Requests](https://www.igvita.com/2011/12/19/dont-push-your-pull-requests/) by Ilya Grigorik.
